Jimmy Calderwood is preparing to axe at least 10 players in a major Pittodrie purge this summer.
The Dons boss has finally lost patience with his flops following the dire 3-1 defeat to Kilmarnock at Rugby Park.
Aberdeen's sudden slump has seen them slip to ninth in the table, 11 points behind third placed Motherwell who also have two games in hand. Calderwood said: "It's now quite clear I have a major rebuilding job on my hands."
Dutch trio Karim Touzani, Dave Bus and Jeffrey de Visscher are likely to be under threat.
Steve Lovell will lead the mass exodus in the close season along with Dan Smith while Stuart Duff, Lee Mair and the experienced Jackie McNamara could also go.
Calderwood would love to keep loan stars Josh Walker and Sone Aluko but the teen pair will return to England this summer.
He added: "The performances we are producing right now aren't good enough for Aberdeen Football Club.
"We've set high standards but they have slipped drastically and I won't settle for second best.
"You learn from every game and it's now apparent we need to make big changes.
"Playing at a great club like Aberdeen comes with extra expectation levels.
"It takes a certain person to handle that and sometimes some individuals can only go so far as a player.
"Maybe a few have been punching above their weight but are now being found and when that happens it's time for surgery.
"I'm preparing for a massive turnaround and it's looking like I'll be into double figures in terms of the number of departures."
Calderwood stayed in Glasgow last night as he heads south of the border to trawl the lower leagues for fresh talent.
Jimmy Nicholl and Sandy Clark will also head off on scouting missions in a bid to net new players.
And Willie Miller has promised his manager will be given cash to fund his red revolution.
"I'm off on my travels again trying to make inroads into strengthening the team," said Calderwood.
"I'll be in England tonight taking in games as we step up our search for fresh talent.
"I've got a chance to look at some games coming up and we'll be watching a lot more in the coming months.
"That's because we need to improve the quality we have to get us back up to where we want to be in terms of our league position."
Calderwood made several changes for the Killie clash including handing keeper Derek Soutar a shock recall.
The former Dundee man is expected to retain his place for Wednesday's match with Motherwell at Pittodrie despite losing three goals at Rugby Park.
"Derek's display didn't have anything to do with us losing three goals," said Calderwood.
"He couldn't do anything to stop them as it was just very bad defending.
"It's up to Derek if he wants to keep his place in the side but I can't blame him at all for what happened against Kilmarnock."
